A compact planar monopole ultra wide band (UWB) antenna is described with coplanar waveguide (CPW) feed for MIMO applications. The radiator and ground plane of the antenna are etched onto a piece of substrate with an overall size of 28.5mm × 42mm × 1.524mm. Implication from simulation shows that the antenna achieves a broad operating bandwidth of 3.2–10.6 GHz for a −10 dB return loss and Comb shaped...
The evolution of Software-Defined Networking and the overall acceptance of protocols such as OpenFlow, demonstrates the added value of decoupling the data plane from the control plane. Existing SDN Controllers enable the expected flexibility from such networks by dynamically providing a fine-grained control of each flow. However, hardware-specific configurations, such as the creation of queues or...
CityFlow is an EU FP7 project, aiming to create a set of multi-autonomous-system OpenFlow experiments on the OFELIA infrastructure to emulate a city of one million inhabitants. In this demo, we demonstrate all of the key components of the CityFlow experimentation stack working together.
Achieving ever-growing Quality of Service (QoS) requirements for business customers is a major concern over the current Internet. However, presently, its architecture and infrastructures are inflexible to meet the demand of increased QoS requirements. OpenFlow, OF-Config (OpenFlow Configuration and Management protocol), and OVSDB (Open vSwitch Database Management protocol) protocols are well-known...
Software defined Networking (SDN) such as Open-Flow decouples the control plane from forwarding devices and embeds it into one or more external entities called controllers. We implemented a framework in OpenFlow through which business customers receive higher Quality of Service (QoS) than best-effort customers in all conditions (e.g. failure conditions). In the demonstration, we stream video clips...
An antenna design is presented for WLAN applications at the center frequencies of 5.2(5.15–5.35) GHz and 5.8(5.725–5.825) GHz. Patch antenna size reduction and reasonable bandwidth is achieved in this work. Four CSSRR have been etched in the ground plane to achieve dual band operation. The proposed antenna provides good flexibility on selection of dual frequency operation by modifying dimension of...
This paper presents a triple band Micro strip slot antenna with SRR shape ring. The prototype antenna is designed and fabricated for wireless communication like IEEE 802.11(g/b/a), WIMAX and GPRS application. The bandwidths are around 5.1% for 1.93GHz (1880-1980), 35.4 % for 2.75 GHz (2400-3100 MHz) and 28% for 5.7GHz (4900-6500MHz).
This paper presents the hardware and software structure of the smart plug in module for automobiles that is fuel efficient as well as power efficient. This module plugs directly into each individual injector and electronically controls the injectors from the Engine Control Unit (ECU). The functions of the modules are acceleration enrichment or deceleration cut-off using pulse width modification (PWM)...
Nowadays, it is desirable in many applications to prevent a device from being affected by an external electromagnetic fields or prevent the electromagnetic field intrusion out of the device. It is coveted to eliminate or reduce the coupling between adjacent devices and these are done by utilizing electromagnetic shields and absorbers. For each of these goals, there are materials that are commonly...
Applications based on animal detection have a very important role in many real life situations. Some of these applications are detection and tracking of animals like elephant in forest for understanding their behavior with the environment, preventing animal vehicle collision on roads, preventing dangerous animal entering in residential area, and many more. In this paper first we will briefly summarize...
Various methods have been proposed in the literature for improving the quality and throughput performance of optical networks, decreasing the bit error rate as well as avoiding saturation of physical layer components. With the increasing demand for high speed Internet and explosive growth in real time applications over the Internet, it is essential to determine the feasibility of establishing light...
This paper focuses on personalization of "user information needs" by applying clustering techniques of data mining. In the current data centric world, it is very important to analyze data properly and draw the crux from the available for effective creation and maintenance of user profiles. This paper throws explains the use of an indispensable technique called Clustering Technique, which...
OpenFlow decouples the control plane functionality from switches, and embeds it into one or more servers called controllers. One of the challenges of OpenFlow is to deploy a network where control and data traffic are transmitted on the same channel (in-band mode). Implementing such an in-band mode is complex, since switches have to search and establish a path to the controller (bootstrapping) through...
This project aims to offer advancing technologies for overall development of the railway station. Allotment of platform to number of trains in less time interval is quite difficult with the token system because this is done just on guess which is not that much efficient and moreover, a minor mistake in estimation may lead to an accident which may bring a lot of lives into danger. So there is a great...
OpenFlow, initially launched as a technology-enabling network and application experimentation in a campus network, has a disruptive potential in designing a flexible network, fostering innovation, reducing complexity and delivering the right economics. This paper focuses on fault tolerance of OpenFlow to deploy it in carrier-grade networks. The carrier-grade network has a strict requirement that the...
In OpenFlow, control and data plane are decoupled from switches/routers. Direct programming of routers/switches is realised from one or more servers (so called controllers). In the case of an in-band OpenFlow network, the control traffic (traffic to or from the controllers) is sent on the same channel used to transport data traffic. Therefore, when a failure occurs along the data traffic path, both...

The Electromyogram signals or EMG signals are generated whenever there is any muscular activity. These signals can be detected easily over the surface of the body. The surface EMG signal detected from voluntarily activated muscles can be used as a control signal for functional neuromuscular electrical stimulation. Muscle signal (EMG) based switching systems may be an option for people who retain some...
